What happened at Mayfair Substation?

The original outage started early on Sunday, 8 November, when transformer cables caught fire. Teams spent Sunday and Monday assessing seven cables, the transformer and electrical panels, and heavy rain slowed the work (SABC News).

On Monday evening, City Power had said it expected gradual restoration by 20:00. Shortly after restoration began at about 18:00, a second explosion hit the substation. The fire department contained it, and the area was cordoned off until it is declared safe for technicians to go back in (City Power alert).

City Power says the cause of the secondary explosion is unknown and will be investigated. Once the site is cleared, teams will assess the damage and work out what material is needed before repairs can resume. Health facilities and water supply in the area are also affected (City Power alert).

When will power be back in Mayfair?

City Power has not given a time. Its alert says "no ETR is currently available at this stage" (City Power). Expect updates on the Hursthill depot WhatsApp channel and on X (@CityPowerJhb).

What should I do while the power is off?

Switch off non-essential appliances so the network is not overloaded when supply returns. Keep fridges closed as much as possible, and check on neighbours who rely on medical equipment. Stay away from substations and cordoned-off areas. City Power has also warned residents not to let anyone in who claims to be from City Power but has no uniform or ID (City Power).
